ABSTRACT
Objective To explore the clinical effects of laparoscopic surgery combined with marvelon,gestrinone and leuprolide in treatment of chronic endometriosis.Methods 50 cases of endometriosis were collected.They were randomly divided into observation group and control group,each group having 25 cases.The control group underwent laparoscopic surgery and the observation group underwent laparoscopic surgery combined marvelon,gestrinone and leuprolide for 3 months.The two groups were compared in clinical effects,recurrence and pregnancy rate,as well as the operation situation.Results The effective rate was 92.0％ (23/25) in the observation group and 64.0％ (16/25) in the control group.The effective rate of observation group was obviously higher than that of the control group(P ＜ 0.05).The recurrence rate was 8.0％ (2/25)in the observation group,and 32.0％ (8/25) in the control group.The recurrence rate of combination group was obviously lower than that of the simple surgical group(P ＜ 0.05).The pregnancy rate was 80.0％ in the observation group;and 48.0％ in the control group after treatment.The pregnancy rate of the observation group was obviously higher than that of the control group(P ＜ 0.05).Liver damage or other adverse reactions didn't occur to any group after the treatment.The mean time of leaving bed was (1.4 ± 0.4) d after operation in the observation group vs (3.6 ± 1.5) d after operation in the control group.Length of hospital stay was (7.6 ± 3.5) d in the observation group vs (11.5 ± 3.9) d in the control group.The difference had statistical significance(all P ＜ 0.05).Conclusions Laparoscopic surgery combined with marvelon,gestrinone and leuprolide is superior to pure surgery group in treatment of endometriosis.It can improve the effective and pregnancy rate,and reduce the recurrence rate.No obvious adverse reactions can be found,thus it is worth of clinical promotion.
ABSTRACT
The aim of this study was to build a gene chip system with surface plasmon resonance (SPR) technique, for which Gamma-peptide nucleic acid (Gamma-PNA) functioned as a probe, in order to improve sensitivity and its specificity. With the use of self-assembled monolayer (SAM) technology, surface chemistry of two-dimensional structure was used. Gamma-PNA was designed according to the bioinformatics, and was plated on the SPR chip modified by SAM. Subsequently, relevant parameters of the experiment were ensured and optimized. The results showed that the performances of Gamma-PNA probe was little affected by the ion concentration of buffer, and it had a strong light signal in a stable state. As the ion concentration was 0, there were still good hybrid reactions; pH value had less influence upon Gamma-PNA probe, and acid environment of buffer could be better. Gamma-PNA probe combined with sensor technologies achieved made the probe with dispensable labels and real-time detection. It also improved the efficiency of the hybridization and the stability, providing the foundation for clinical application.
